The external popliteal or peroneal nerve passes along the outer part of the 

 popliteal space close to the tendon of the Biceps muscle as far as the head of the 

 fibula. (Plate LXXVIII.) It is about half as large as the popliteal nerve. It 

 gives (1) articular branches to the knee-joint (superior and inferior ex- 

 ternal) also recurrent articular branch to the superior tibio-fibular articulation 

 (2) Cutaneous branches which supply the integument along the back part 

 and outer side of the leg. (3) Communicans peronei which joins the com- 

 municans poplitei to form the short saphenous nerve. Museulo-eutaneous

which begins on the head of the fibula and passes down between the Peronei 

 muscles and the Extensor brevis digitorum pierces the deep fascia a1 the lower 

 one-third of the leg on its front and outer side. This nerve supplies the I'er- 

 oneus Longus, Peroneus brevis, and the integumenl mi the dorsum of the foot. 



The INTERNAL TERMINAL BRANCH of the nuiselilo-rutaneous nerve passes in 

 front of the ankle-joint and divides into two branches. The inner branch 

 passes to the inner side of the great toe and sends twigs to the integumenl on 

 the inner side of the foot. The outer branch passes to the base of the cleft
